[libvirt] libvirt-java, deprecated methods?

Hi, I'm playing around with libvirt-0.6.5 and libvirt-java-0.2.1 these days. It looks very interesting, but I think I may have found a bug: .... conn = new Connect("xen://node02", false); .... conn.setDom0Memory(512000) gives: exception caught:org.libvirt.LibvirtException: invalid domain pointer in virDomainSetMemory level:VIR_ERR_ERROR code:VIR_ERR_INVALID_DOMAIN domain:VIR_FROM_DOM hasConn:false hasDom:false hasNet:false message:invalid domain pointer in virDomainSetMemory str1:invalid domain pointer in %s str2:virDomainSetMemory str3:null int1:0 int2:0 Furthermore, f.e. conn.GetHypervisorVersion(conn.getType()) gives: exception caught:org.libvirt.LibvirtException: this function is not supported by the hypervisor: Xen level:VIR_ERR_ERROR code:VIR_ERR_NO_SUPPORT domain:VIR_FROM_NONE hasConn:false hasDom:false hasNet:false message:this function is not supported by the hypervisor: Xen str1:this function is not supported by the hypervisor: %s str2:Xen str3:null int1:0 int2:0 But Domain dom0=conn.domainLookupByID(0); //domainLookupByName("Domain-0"); too DomainInfo dom0info = dom0.getInfo(); .... dom0.setMemory(256000); .... works without glitches and does the job (btw, I can't see any effect of setMaxMemory() on Xen?) Is it possible that there are some inconsistences between libvirt-java and libvirt? Since libvirt-java wasn't updated approx. 1y, I assume that. Thanks for feedback, kr, thomas
